Generac 7077 Guardian Standby Generator 20kW 3-Phase Air-Cooled

The Generac Guardian 7077 is a commercial-grade 20kW air-cooled automatic standby generator designed for 3-phase power systems (208V). It provides reliable backup electricity for small commercial buildings, light industrial facilities, multi-unit properties, and specialized residential installations that require 3-phase electrical distribution.

Powered by a Generac G-Force 999cc OHVI engine, the 7077 delivers stable, clean power with True Power™ technology (<5% THD), ensuring safe operation for sensitive electronics and connected equipment. It runs on natural gas or propane (LP) and automatically starts within seconds of a utility outage, restoring power through a compatible automatic transfer switch system.

Unlike standard single-phase home standby units, this model is specifically designed for 208V 3-phase applications, making it ideal for equipment loads that require balanced multi-phase distribution.
